libnvdimm/labels: Introduce the concept of multi-range namespace labels
The CXL specification defines a mechanism for namespaces to be comprised
of multiple dis-contiguous ranges. Introduce that concept to the legacy
NVDIMM namespace implementation with a new nsl_set_nrange() helper, that
sets the number of ranges to 1. Once the NVDIMM subsystem supports CXL
labels and updates its namespace capacity provisioning for
dis-contiguous support nsl_set_nrange() can be updated, but in the
meantime CXL label validation requires nrange be non-zero.
